A friend who is like a sister.

a term used to describe your vape or anything you wouldn’t want your parents to know about

Your bestesting friend. Better than any friend. Who's been your friend for so long you might as well be sisters. You hate her you love her. She's your sister.

A person who is always there for you. Similar to a best friend but more, someone you hope will be in your life forever, she will be in your wedding and you two know eachother like sisters would.
Not developed with time, a person you meet and just know they are your sister friend.

Your sister, your only sister. She is your sister but a friend and the most amazing one at that.

First slurred out when I was drunk because there was no one word invented for her yet.

Sisterfriend is the best of both worlds: First she is your blood- Second she is your friend-confidant-reality check. Sometimes you fight and sometimes you get ridiculous with each other. She is a friend that will always be there because she has to- she's your sister duh!!!

Sister-friends are girls that are so close, they could be sisters.. They can't live without each other. Side by side or miles apart, they will always be close. To each other, they are unforgettable. They act weird and smack butts without giving it a second thought. When they are happy, you are. When they feel pain.. you do. Living without them isn't an option. They are you're life. <3 You love them.
